- each guide surface has an arcuate convex surface, semicircular in the present example. Other shapes are also possible, including V-shaped profiles and others. While in the present example the guide surfaces 210 and 212 face each other, they can also be configured to face away from each other and engage complementary surfaces for helping to guide the wringing assembly toward and away from the mop head assembly 400 .
- the guidepost 206 is formed as a C-shaped profile, which may be metal or plastic.
- the guidepost has a relatively wide bottom wall 214 ( FIG. 5 , “bottom” being the recessed portion of the C-shaped profile) and relatively short sidewalls 216 forming a shallow cavity in the profile.
- Other profiles for the guidepost can also be used.
- the bottom wall 214 is perforated to decrease the weight of the structure.
- the guideposts 206 and 208 extend longitudinally to and support a wringing structure 220 , mounted to and supported on end portions of the guideposts.

- the body has third and fourth sides 232 and 234 , in the present example relatively shorter than the first and second sides.
- the third and fourth sides support and maintain the first and second sides relatively fixed and spaced apart.
- the first and second sides support and allow pivoting of respective pairs of rollers 236 and 238 , and 240 and 242 .

- the rollers 236 , 238 , 240 and 242 provide four points or concentration areas of applying pressure to the mop head assembly.
- the wringing structure 220 is configured so that the rollers can rotate about their respective axes, and are substantially rigidly maintained in their respective spacings, to reliably apply pressure to the mop head assembly as desired.
- the rollers 236 and 240 are positioned opposite each other and substantially in the same plane, and rollers 238 and 242 are positioned opposite each other and in substantially the same plane, which is the same plane as for rollers 236 and 240 . While they need not be opposite each other or in the same plane, such configuration permits a reliable and balanced wringing function.
- Each pair of rollers 236 and 238 , and 240 and 242 are spaced apart from each other corresponding to spacing of contact surfaces on the mop head assembly, described more fully below.
- the longitudinal center of a roller surface is aligned with its respective contact surface on the mop head assembly. Wringing functions can also be achieved additionally or alternatively with scraping surfaces or other friction surfaces.

Additionally, the rollers can have profiles including side surfaces that may be used to wring side portions of a mop assembly, for example edge or outside surfaces of respective rollers facing away from the handle and/or guideposts and configured to contact portions of the mop material.
- the rollers can be mounted in such a way as to allow adjustability of their positions in the wringing structure 220 . Adjustability can be also incorporated into the pivot block 420 , to allow adjustment of the spacing distance between the facing half plates. Such adjustability can allow variations in wringing pressure applied to the mop head assembly or mop size variations.
- the wringing structure 220 in the illustrated configuration includes a pair of oppositely positioned and facing initiation rollers 242 and 244 .
- the initiation rollers are positioned vertically spaced apart from and outboard of the pressure or wringing rollers 236 , 238 , 240 and 242 , and are positioned and configured to make early contact with corresponding surfaces on the mop head assembly, described more fully below, to initiate folding or movement of the wings of the mop head assembly toward each other.
- the initiation rollers start the movement of the wings toward each other.
- the wringing structure 220 includes alignment or centering surfaces 246 , 248 , 250 and 252 .
- the alignment surfaces are configured and positioned to contact and cam any surface of the mop head assembly that may be adjacent to the respective surface as a result of the mop head being tilted or pivoted out of a plane perpendicular to the handle 102 about the axis 118 .
- the alignment surfaces help to align the mop head assembly prior to or during the initiation of folding or movement of the wings toward each other. Alignment helps to ensure that the wings are facing each other and fold toward an axis coaxial with the axis of the handle 102 for optimal wringing.
- each of the initiation rollers 242 and 244 or their adjacent surfaces 254 on the wringing structure will contact the adjacent surfaces on the mop assembly if the mop assembly is pivoted out of a plane perpendicular to the handle 102 about the axis 116 ( FIG. 4 ).

- other means can also be used to wring moisture from the side surfaces of the mop attachment.
- rollers (not shown) can be mounted at the surfaces 298 and facing perpendicular to the pressure rollers 236 , 238 , 240 and 242 , and/or rollers or other surfaces can be profiled in such a way as to allow wringing or pressing of moisture from surfaces of the mop attachment.
- the wringing assembly 200 also includes a guide 260 ( FIGS. 1-4 and 6-9 ).
- the guide helps to guide the wringing structure 220 toward and away from the mop head assembly 400 and along the handle 102 .

As illustrated, the raised wringing surfaces are at the perimeter edges.
- the upper surface of the vertically-extending wall 432 can have a number of configurations, depending in part on the desired pressure profile to be applied to the bi-plate during the wringing operation.
- the wall 432 can have a constant height from the upper surface 428 , but in the illustrated examples, the height of the wall 432 increases with distance from the hinge structure 414 , and also as illustrated, the increase is relatively constant. Such a configuration applies greater pressure as the wringing action progresses.
- the walls 432 extend substantially the entire length of the bi-plate.
- External surfaces of the vertically-extending wall 432 include convex support structures in the form of convex walls 434 extending laterally outward from the respective wall 432 .
- the convex walls 434 help cleaning coving and other similar surface profiles, and also help to reinforce the vertically extending walls.
- a mop assembly 100 ( FIGS. 15-18 ) will have the handle 102 inserted through the handgrip 202 and the opening 296 in the top of the guide block 280 and into the adapter and secured with the nut 106 .
- the guide 260 is already secured to the adapter through the fastener 272 and the block 268 , to mount the wringing assembly on the adapter.
- the user grasps the handle 102 and the manual grip 202 and moves the manual grip distally along the handle, thereby moving the wringing assembly 200 distally toward the mop head assembly 400 .
- the guide 260 and the guide surfaces 290 , 292 and 294 help to guide the guideposts and keep the wringing assembly coaxial with the handle.
- the mop head assembly is self-aligned by the action of any contact between the mop head assembly and the cam surfaces 246 , 248 , 250 and 252 , and 254 .
- the initiation rollers 242 and 244 contact the cam surfaces 426 on the half plates, and start folding the half plates toward each other and toward a central axis 126 of the handle ( FIG. 15 ). Once contact occurs, continued forward or distal progress of the wringing assembly continues to push the initiation rollers 242 and 244 against the cam surfaces 426 and pivot the half plates 402 and 404 closer to each other about their respective hinges.
- the initiation rollers 242 and 244 move further along the cam surfaces 426 , and the pressure rollers 236 , 238 , 240 and 244 contact the corresponding wringing surfaces 430 to press the spaced apart half plates toward each other.
- further progress applies greater pressure because of the increasing height of the wringing surfaces 430 with distance away from the hinge sides ( FIGS. 17-18 ).
- the mop material is squeezed to remove additional moisture as desired.
- the amount of wringing will be a function of the relative distance the wringing assembly is progressed along the handle and of the surface profile of the wringing surfaces 430 .
- Suitable markings can be placed on the handle to provide a relative measure of the wringing as a function of position along the handle. Additionally, one or more stops can be applied to physically limit the progress of the wringing assembly along the handle, and therefore the wringing action. Such markings and/or physical limits may also be used with different sizes of mop assemblies to account for variations in the lengths of the half plates. Alternatively, or additionally, different lengths of guideposts can be used for selected mop head assemblies, for example as a function of the length of the half plates.
- the initiation rollers 242 and 244 can be omitted in favor of the adjacent surfaces, which then contact the respective half plates, if the cam surfaces are sufficiently high to be contacted prior to the pressure rollers contacting the wringing surfaces 430 . If not, the pressure rollers contact the wringing surfaces to bias the half plates toward each other and eventually begin wringing.
